However, circulating FABP5, similar to FABP4, has been reported to be detected at levels of about one tenth or less of FABP4 concentrations, and FABP5 level has been shown to be associated with components of metabolic syndrome, though the correlation is not as strong as that of FABP4 [25, 36, 37]. The gene discussed is FABP4; the disease is metabolic syndrome.
